To @ZZ whom it may concern.-

Beit known that I, JOHN E. SALES, a citi- Zen of the United States, and a resident of Wrangell, in the District of Alaska, have invented a new and improved Rock-Drill, of which the following is a full, clear, and exact description.

My invention relates to drills, and especially to those adapted for operating upon rock and like substances. Its principal objects are to provide such an apparatus which may be readily positioned Aand eliiciently operated with a minimum number of attendants.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a side elevation of one embodiment of my invention, parts being broken away. Fig. 2 is a top plan view thereof. Fig. 3 is a transverse sectional detail on the line 3 3 of Fig. 1. Fig. 4 is a detail in broken side elevation of the locking mechanism for the tackle, and Fig. 5 is a detail perspective view of the brake mechanism.

The apparatus is preferably supported upon a car 10, having wheels 11, adapted to run upon rails 12. In a circular opening in the top ofthe car is situated a turn-table having a central shaft 14 rotatable in a bearing yteet upon the car, and rolls 15, mounted near its periphery and running upon a track 16, carried upon brackets 17 within the opening. The turn-table is shown as provided with peri heral teeth 18, with which mesh the of a pinion 19, fixed upon a vertical shaft 20, rotatably mounted in the floor of the car and havinga crank 21, by which it may be turned to rotate the table aboutits axis.

Upon the upper surface of the turn-table, between its center and circumference, are pairs of alined lugs 22 22, upon which is pivoted a main Jframe. This frame may comprise a carrier-bar 23, swinging upon the lugs and havin a central upright 24, which includes space side bars connected at their upper extremities by an integral cross-bar. From the u per end of the upright and from the carrierar project rods 25, which supportan open headV 26. Upon this head is mounted a secondary frame, including an inner head 27, from the upper and lower sides of which project trunnions 27a, turning in the head 26. From the inner head at its top and bottom toward the table project rods 28, which at their opposite extremities are connected to top and bottom cross-bars 29 and 30, respectively, from a vertical connecting-bar 31. The secondary frame also includes a supporting-bar 32, having lateral trunnions 33 33 pivoted in the sides of the head 27 and permitting saidsupporting-bar to move in planes substantially at right angles to those in which the secondary frame may swing. Near the opposite ends of the supporting-bar are upward extensions 34 34a, from the top of which project lateral arms 35, connected by supporting rods 36. These rods carry a casing 37, inclosin the motor or operating mechanism for the rill 38, which 'projects forwardly and is guided by the extension 34, in which it rotates. .Extending through the casing and having threaded engagement therewith is a screw 39, which is journaled in the supporting-bar extensions and has at its inner end a crank 40, by which it may be rotated, this serving to move the motor-casing bodily along the su portingrods, and thus advance or with drill.

The main frame may be swung upon its supporting-pivots by means of connections extending between the turn-table and the center upright, thisconveniently consisting of tackle having blocks 4 1 and 42j, supported upon eyes carried by the table and upright, respectively, over which blocks passes a rope 43, fixed at one end to the block 41 and at the opposite extremity to a drum 44, rotatably mounte between the side bars of the upright. The'spindle of this drum may be provided with a crank y45 and with a toothed wheel 46, with whichwheel coacts locking mechanism which may comprise a pair of members 47 47, pivoted together upon the outside of one of the side bars and each having inwardly-extendin projections to enter between'the teeth, anrgl thus hold the drum against rotation and the frame in itsv adjusted osition. The en agement between the loc lng members an toothed wheel is preferably normally maintained by means oi' a spring 48, which passes inside the pivotpin of the members and exerts its tension against them. y

Means are' provided for ycontrolling the vertical :and horizontal movements of the drill, these being secured by the swinging of `the secondary frame and the supporting-bar raw theupon their trunnions. For this purpose the carrier-bar 23 has at its inner side a gear-segment 49, with which meshes a pinion 50, carried by a shaft 51, journaled in the cross-bar 30 and in a lug 52 from the inner side of the connecting-bar 31.. The shaft has at its upper endy a crank 53, by which it may be rotated to swing the secondary frame and drill horizontally. At the outer edge of the bar '31 is a gear-segment 54, in engagement with a pinion 55, fixed upon a shaft 56, j ournaled in the supporting-bar and having acrank 57. The turning of this crank ef'ects a vertical movement' of the drill .by the swinging of the supporting-bar. Both the pinions and 55 may be iixed in position to hold the drill in adjustment by locking members 58 58 coactlng with the pinion-teeth and being similarly supported and operated to the members 47, previously described.

The drill-motor may be conveniently `driven by compressed air, it having connected with it a hose or flexible transmitting means 59, extending from a suitable source of pressure. The slack of this hose may rest upon the car, it then passing'about a drum 60, rotatably mounted upon standards a, projecting fro-rn the car-floor. The drum maybe geared to one of the ear-axles by a chain 61, passing over sprocket-wheels 62. As the car is moved the hose is thus automatically paid out or dra-Wn in, obviating the necessity for handling it.

Secured to a rock-shaft 62a is sho-wn a lee ver 63, which may be fixed in position Vby latch mechanism 64, coacting with a toothed sector1v 64a. Toeach end of the shaft is secured an arm 64b', the-arm being secured to the shaft at its center of length to form oppositely-pro-jecting members, and to the lower memberof the arm is pivoted a link 6'5,which carries a brake-block 66,' having converging faces which conform to the periphery ofv one of the car-wheels and to the track, these faces `being preferably roughened to secure more effective frictiona engagement. Upon an arm 67, pivoted upon each side of the car near the wheels at thel opposite end, is carried a similar blo-ek, this arm and the upper member of the corresponding arm 64b' being connected by a link 68, so that the two brakeblocks may be moved in unison. When these blocks are thrust between the` rail and wheels by moving the leverrearward, the car is held against movement to allow the projection of the drill into the Work. When desired, they may be quickly and readily released by swinging the lever 1n the opposite direction.

In use the car is pushed forward upon the rails to the face which is to behoperated upon, the brakes applied, and an initial positioning secured by rotating the turnetable and swing ing the main frame by means of its tackle, thus securing both a horizontal and a vertical adjustment of the drill. Said drill at the beginning of the operation is drawn in or its motor-casing is at the inner ends of the supporting-bars, as is shown in Figs. 1 and 2 of the drawings. It is now advanced into the work by turning the crank of the screw, its length being sufficientto enable the hole to be drilled to its full depth without changing drills, this being only necessary in my improved apparatus when the working portions become dulled or it is desired to use a different length to meet special conditions. The first hole having been completed, the drill may be withdrawn by reversing the rotation of the screw, and then by means of the cranks 53 and 57 the secondary frame and supporting-bar are moved to bring the drill into position for making the next hole, when table, means for adjusting said frame, a secondaryfrarne pivoted in the main frame to 'lng in a plane at right angles to the plane of ovement of the said frame, means for adjusting the secondary frame, a supporting bar pivoted in the secondary frame to swing in aplane at right angles te the planeof ino-vement of the secondary frame, said bar carrying guide-rods, means for adjusting the su porting-bar, a motor mounted vto slide on the uide-rods of the supportin bar, and means l or sliding the motor on sai( bars.
